Re: Artemis remove divert - message loss

[Justin Bertram <jb...@apache.org>]

It's worth noting that questions like this should be directed to the
ActiveMQ users mailing list rather than the dev list.

In any event, I wouldn't expect these operations to lead to any message
loss. However, I'm puzzled why you'd invoke pause() and resume() on the
address. This has no impact on the divert. It only stops the delivery of
messages from the queues on the address to any connected consumers. I'd
recommend simplifying your process to just destroyDivert(). It should be
functionally equivalent and just 1 step instead of 3.
